TL;DR
A jumbo clip (also called a binder clip or butterfly clip) is a large spring-loaded metal clip that clamps documents, bags, packaging, and materials together without punching holes. Jinxinyu Hardware offers seven standard sizes from JC50 (50mm) to JC146 (146mm), in round-back (R) and flat-back (C) designs. Surface finishes include bright nickel, gold, rose gold, antique brass, matte black, and custom Pantone colors. Applications range from office document filing and food bag sealing to brand gift customization and stationery retail. OEM support and low MOQ available from our Foshan factory.
1、What Is a Jumbo Clip?
A jumbo clip (binder clip / butterfly clip) is a heavy-duty spring-loaded metal clamp with two folding wire handles (wings). Folding the wings outward opens the jaw; releasing them allows the spring tension to clamp the material firmly in place. No punching, no adhesive, no damage to the material being held.
Core advantages of jumbo clips:
- No hole-punching required: clamps directly onto any material without marking or tearing
- Reusable: designed for thousands of open-close cycles without losing spring tension
- Strong clamping force: handles thick stacks of paper, card, packaging, and fabric
- Versatile: works on documents, food bags, photo prints, fabric, and more
- Highly customizable: wide range of colors and branding options for promotional and gift products
Primary application areas:
- Office document organization and temporary archiving
- Food bag and snack packet sealing
- Temporary fixing of photos, posters, and blueprints
- Craft and DIY material holding
- Branded corporate gifts and promotional stationery
- Large-format clipboard top clips

- Confirm surface finish: Bright Nickel for standard commercial orders; Gold, Rose Gold, or Matte Black for branded gift and premium stationery programs
- Confirm quantity and MOQ: standard Bright Nickel sizes are stocked and support small minimums; custom colors require MOQ confirmation before ordering
7、FAQ: Jumbo Clips
Q1: What is the difference between a jumbo clip and a binder clip?
Jumbo clip and binder clip refer to the same product type — a spring-loaded metal clamp with folding wire handles. The term ‘jumbo clip’ typically emphasizes the larger size variants (50mm and above), while ‘binder clip’ is used broadly across all sizes from small (19mm) to extra-large (51mm+). In international trade, the two terms are used interchangeably.
Q2: How much stronger is a JC146 than a JC50?
Clamping force scales proportionally with clip size. A JC50 (50mm) is designed for light document bundles — perhaps 50-150 sheets of paper. A JC146 (146mm) delivers dramatically greater force, capable of holding material stacks up to approximately 50mm thick (roughly 500 sheets of 80gsm paper). Always select a size with 10-15% headroom above your actual clamping requirement to ensure a secure hold.
Q3: Are jumbo clips safe for food bag sealing?
Yes, with some important caveats. Choose clips with RoHS-certified plating to ensure the surface materials are free from harmful heavy metals. Use the clip on the bag seal only — avoid direct contact with food. In humid or wet environments, choose finishes with stronger corrosion resistance (such as matte nickel or special protective coatings). Jinxinyu jumbo clips are RoHS-certified; test reports are available on request.
Q4: Can a brand logo be printed or engraved on jumbo clips?
Yes. Jinxinyu supports brand customization on jumbo clip backs and wing surfaces. Common processes include silk screen printing, laser engraving, and embossing. Branded jumbo clips are very popular in European and North American corporate gift markets. Minimum order quantities and process feasibility vary by clip model and logo design — contact our sales team with your artwork for a quote.
Q5: Which finish colors sell best in international markets?
Bright Nickel (silver) remains the global volume leader, appropriate for virtually all commercial environments. Rose Gold and Matte Black have shown strong growth in European and North American premium stationery retail in recent years — common in specialty stationery shops and branded gift sets. Gold is consistently popular in Middle Eastern and Asian gift markets. For first-time buyers, starting with Bright Nickel in volume and testing one or two custom colors in smaller quantities is the recommended approach.
Q6: What is the minimum order quantity for custom color jumbo clips?
Standard Bright Nickel jumbo clips are held in stock across all seven sizes and support flexible minimum orders suitable for small and mid-size buyers. Custom color variants (Rose Gold, Matte Black, Gold, etc.) and logo-printed clips carry minimum order quantities that vary by size and color. Contact our sales team for current MOQ figures and per-unit pricing for your specific requirement.
Q7: What certifications are required to export jumbo clips to Europe and North America?
The primary requirements for European and North American import compliance are RoHS certification (restricting hazardous substances including lead, mercury, and cadmium) and REACH compliance. Jinxinyu jumbo clips pass both RoHS testing and 48-hour salt spray testing. Official test reports are provided with every order to support import documentation and customs clearance.
